Menelaus rages, “Our men will starve and we will never make it to Troy if you refuse. You promised you would help me. My wife has been abducted and you pledged your help. May the gods never forgive you.”
“This is my daughter.”

You can block Menelaus. You grew up with him and you know how to defeat him. Will you fight him? Will you allow him to send the letter? Will you do it yourself?
